For fault E041
If the pressure drops below the safety threshold of 0.3 bar the boiler displays
the fault code <<E041 water transducer load the system>> for a transitional
time of 30sec.
When the transitional time has finished, if the fault persists the fault code E040
is displayed.
When the boiler has fault E040 manual loading should be carried out using the
filler tap ( A ) until the pressure is between 1 and 1.5 bar.
Then press RESET.

These are temporary alarms that if they occur 6 times in an hour they become definitive; the E097 alarm is dis-
played and is followed by post-purging for 45 seconds at the fan's maximum speed.

These are temporary alarms that if they occur several times in an hour they become definitive; the last error to
occur is displayed and is followed by a post-purging of 5 minutes at the fan's maximum speed. It is not possible to
release the alarm before the end of the post-purging unless the boiler's power supply is switched off.
Close the filling tap, making sure to hear the mechanical snap.

If the drop in pressure is very frequent, contact the Technical Assistance
Centre.
For fault E060
The boiler is working normally, but does not provide any stability of the
domestic hot water temperature that, in any event, is supplied at a tempera-
ture of around 50°C. The intervention of the Technical Assistance Service
is required.
For fault E091
The boiler has an auto-diagnostic system which, based on the total number
of hours in certain operating conditions, can signal the need to clean the
primary exchanger.
The intervention of the Technical Assistance Service is required.
